Does the original contract I signed stand? Or is the second copy a legal binding document (without my signature)?

My landlord said the lease was good for a year in the email when I first contacted her about the property. Then when we met up, I was told that if I had to relocate to anywhere else, I could leave without the penalty of losing my deposit. On the original lease agreement I signed, it stated that it is month-to-month tenancy and all I had to give was 30 day notice to move out and the landlord's supposed to give me my deposit back. After I signed the original lease, LL did not provide me the copy of the signed lease. More than a month later, after bugging LL multiple times to obtain the lease copy, I was finally provided with the lease but it did not have my signature on it. And the section where it said it was month-to-month was changed to a year lease (I did not have any way of knowing the difference because I was never given the original lease, I found this out through the court where she filed for eviction proceedings). Now, I notified LL two months before I moved out. When I notified LL, I asked for the deposit back. The LL refused and said I was breaking the lease. So I did not pay the last month's rent and said LL could keep the deposit as rent (I did not damage anything other than regular wear and tear). The LL filed the eviction, first cause hearing was dismissed because I had already moved out. Now for the second hearing, does the original contract I signed stand? Or is the second copy a legal binding document (without my signature)? P.S. While I lived there we did not get along - I complained about the other tenant's noise and the LL didn't want to do anything about it. So we were both nasty to each other (I admit I was nasty too - if that matters in determining whether the lease is binding).
